Wall Thickness Tester, 0.5-5.0mm

Here's a super handy wall-thickness test gauge. See where your printer's at with 19 thicknesses--0.5 to 5.0mm, in 0.25mm increments.
Again that's 0.5, 0.8, 1.0, 1.3. 1.5, 1.8, 2.0, 2.3, 2.5, 2.8, 3.0, 3.3, 3.5, 3.8, 4.0, 4.3, 4.5, 4.8, and 5.0mm. Also test wall fill completeness and wall strength versus height.
